## Why ga4_create_data_stream is rated Medium

This tool creates new Google Analytics 4 data streams, which modifies the analytics configuration reversibly. It does not execute arbitrary code, delete data, or move money. While it creates configuration objects that could theoretically be misused to inject tracking into applications, the primary risk is data creation and modification of analytics setup.

From the tool's own definition: "Tool description states 'GA4 property에 data stream 생성' (create data stream in GA4 property). The verb 'create' and the action of generating new analytics data streams (returning measurementId or firebaseAppId) indicate data creation."
